ABSTRACT
An interventional pulmonologist possesses expertise in minimally invasive diagnostic and therapeutic procedures involving the airways, lungs and pleura. A malignant pleural effusion (MPE), which occurs in 20% of cancer patients, can be a daunting diagnostic challenge insofar as the pleural cavity is a closed cavity. In these patients, treatment may consequently be delayed before a precise diagnosis can be given. In the meantime, an interventional pulmonologist is called upon to carry out a wide range of examinations in order to establish the etiological diagnosis and to treat the symptoms of an MPE patient. Classical medical thoracoscopy, also called "pleuroscopy", is the reference method in MPE diagnosis because it allows visualization of the pleural cavity, pleural biopsy under direct visual control, providing excellent diagnostic yield. Over the past decade, new diagnostic methods have emerged, such as ultrasound-guided biopsy, as well as different interventions, such as indwelling pleural catheters, aimed at improving the quality of life of MPE patients, for whom therapeutic options are limited. The objective of this review of the literature is to point out the role of the interventional pulmonologist in the management of MPE by detailing the various diagnostic and therapeutic methods he possesses at the present time.

Silicosis and sarcoidosis are two very distinct entities in the literature. All the additional non-invasive examinations, including the chest CT scan, often do not differentiate them. The history, including occupational exposure to identified silica particles, is a discriminating factor. However, due to the pathogenic power of silica, it would be possible to have the simultaneous development of these two pathologies in the same patient. To illustrate this situation, here is the case of a 62-year-old patient, who presented initially with a picture of dyspnea and productive cough. The chest CT showed micronodular peribronchovascular infiltrates and mediastinal lymphadenopathy. The other additional examinations did not find anything specific. In the diagnostic process, the patient had multiple endoscopic samples which did not make it possible to be conclusive on one or the other of these pathologies. He therefore underwent a surgical lung biopsy which revealed histological lesions compatible with the two pathologies. Recent studies suggest that inhaled particles, especially silica, could be responsible for the pattern of sarcoidosis. However, it is difficult to say whether, in this case, silica was responsible for the development of sarcoidosis.
